Yeah, the text says every subsequent round, so there wouldn't be a save on the first round. Aside from the ease of optimizing skill checks, you could poke the dragon, make it dance, and at that point, who cares if it makes its save? You can do it again every round, rendering any non-mindless or mind-blanked enemy useless.
